Here's another, and I am sure there arev plenty more.

Aqua Signal Series 25 stern light at West Marine: $23. At SailNet: under
$10. At Defender: about $15. But SailNet charges more than $10 for shipping
and Defender charges nearly $5 for shipping to my ZIP.

So what's the price of instant gratification -- walking into the store and
walking out with the item? Plus tax.
